Kuyini ukusetshenziswa kwemojuli ye-PID yokushisa yesilawuli samandla we-scr

Izilawuli zamandlaasetshenziswa kakhulu ekushiseni kukagesi, okunganciphisa ukushaqeka kwamanje ku-heater futhi kunikeze ukulawula okunembile kwezinga lokushisa.Kusekelwe eminyakeni eminingi yokuhlangenwe nakho okucebileisilawuli samandlaukuthuthukiswa kanye nokusetshenziswa, inkampani yethu ithuthukise aisilawuli samandlange-module eyakhelwe ngaphakathi ye-PID yokulawula izinga lokushisa.Lo mkhiqizo ungasetshenziswa kabanzi ekusetshenzisweni komthwalo ophikisayo nowokuzuzisa, umshini wokulawula ukushisa kagesi ofanelekile.

Ngeisilawuli samandla se-thyristorImojula yokulawula izinga lokushisa eyakhelwe ngaphakathi ye-PID, awudingi ukwengeza imitha yokulawula izinga lokushisa eyengeziwe ukuze kuguqulwe izinga lokushisa, ulondoloze izindleko zakho zokutshala imali.Ngesikhathi esifanayo, ngemva kwemodyuli yokulawula izinga lokushisa ye-PID eyakhelwe ngaphakathi, ukwakheka komkhiqizo kufushane futhi kuthuthukisa ubuhle bomkhiqizo.Xhuma ngokuqondile i-PT100, K, S, B, E, R, N isignali yenzwa yakho kumshiniisilawuli samandla 

Iscr amandla umlawuliizohlonza isiginali bese idlulisela ku-4-20mA/0-5v/0-10v ukuze ibe isilawuli sokuphumayo.

Isimiso sokulawula izinga lokushisa kwe-PID: inani lempendulo yezinga lokushisa elitholiwe liguqulwa libe isignali kagesi, futhi isignali kagesi ikhishwa kunani lokulawula elimisiwe ngemva kokulungiswa kwe-PID kanye nenani lokuchezuka litholwa.Inani lokuchezuka litholwa ngohlelo lokubala futhi inani lokulawula lifakwa ku-actuator.I-actuator ilungisa amapharamitha afanele wesekethe yokunikezwa kwamandla ngokwemiyalo, ibona ukulawulwa kwamandla okushisa komthwalo, futhi ekugcineni ifinyelela umgomo wokulawula izinga lokushisa.

I-Nokel Electric iyingcwetiisilawuli samandlainkampani yokuklama nokukhiqiza.Ngokusekelwe eminyakeni engu-20 yokuhlangenwe nakho kokuthuthukiswa kweplathifomu ye-SCR, ithuthukise ukusebenza okuphezulu kakhuluisilawuli samandla, ingashintshwa ku-voltage 220--1140v, 25--2000A ukumelana nomthwalo we-inductive, izuze imiphumela emihle kakhulu embonini yokushisa kagesi.Imikhiqizo ye-Noker Electric ibonakala nge:

1. Ukusebenza okuphezulu okwakhelwe ngaphakathi, isilawuli esincane samandla amancane;
2. Izici ze-peripheral;
2.1.Ukusekela 4-20mA kanye 0-5V/10v ezimbili inikezwe;
2.2.Okokufaka okubili kokushintsha;
2.3.Ububanzi obubanzi be-primary loop voltage (AC110--440V);
3. Isixazululo sokupholisa esisebenzayo, usayizi omncane kangako, isisindo esilula;
4. Umsebenzi we-alamu osebenzayo;

4.1.Ukuhluleka kwesigaba;
4.2.Ukushisa ngokweqile;
4.3 I-Overcurrent;
4.4.Ikhefu lokulayisha;
5. Okukhiphayo okudluliswayo okukodwa, 3A AC250V, 3A DC30V;
6. Ukwenza lula ukulawula okumaphakathi RS485 ukuxhumana;
7. Okukhethwa kukho kwe-analogue okukhiphayo, isilawuli se-PID esakhelwe ngaphakathi.

Uma unombuzo, sicela ukhululeke ukuxhumana nathi, sizokunikeza isisombululo.
